Viewing on the iPhone used to work. Rough, but usable, at least enough so I could determine if it was worth viewing on a computer. Some months back things changed and many Instructables don't work at all.

Agreed. The guides used to be viewable from my iPhone but no longer appear at all. Each instructable shows up blank with just the site header logo viewable. It isn't just when loading pages from Emails, the same thing happens when searching and clicking on a guide. A moble version would be great

I'm having the same issues, it worked at onetime but not now. when I try to do to the project write ups it just leads to an ad then stops there. I'm not aware of any settings that would affect it but I'll dig around a bit.
